The interview in these days, I feel that the whole grasp of spring is still very weak. So we need to continue to strengthen.Here to explain the spring of these several aspects of the test, but the actual feeling is still wrong, this problem I think the need to really read the spring source code to say something to make sense. This kind of interview asks the law, also only is the interview the question law, to the actual grasp still has no slightest meaning. So I think there is a chance to read t

. Implementing Comet-style WEB applications, while ensuring scalability on browsers and servers, is only possible in recent years. Later in this article, we'll look at how some popular Java WEB servers support Scalable Comet architectures, but first let's see why we're creating Comet applications and the common design patterns that we use to implement them. motives for using CometThere is no doubt about the success of the HTTP protocol. It is the basi

Weave in (Weaving)The process of applying facets to a target object to create a new proxy object usually occurs in the following time:(1) Compile time: When a class file is compiled, this requires a special compiler to do so, such as AspectJ's weaving compiler(2) class loading: Use special ClassLoader to enhance the class's byte code before the

Use dynamic and ExpandoObject In the MVC controller to implement data escape output, mvcexpandoobject In many cases, we define table fields in the database and the actual content displayed on the page, which is often not very matched. Page data may be a combination of multiple table data, therefore, in addition to table design considerations, we also need to consider data presentation processing. For general processing, some foreign key fields need to

I all articles first published in the personal blog, welcome attention, Address: http://blog.isming.me ? Material design really looks good, the animation effect is really very practical. I also wrote some articles about how to write material-style programs, but a lot of them are new APIs, and the lower version doesn't have these APIs, and we can't use them. But don't be discouraged, Google official, and some Daniel, to provide us with some procedures, let us in the lower version can

The Tab switch effect is widely used in today's web pages, including click switch, sliding switch, latency switch, and automatic switch. In this blog, we use native JavaScript to implement the Tab click switch effect.

Jquery is often used. ui. tabs label. For example, we can put Backup management on a page, which has two tabs for backup and restoration respectively. However, this page will be bloated every time a backup Management page is requested, the server will upload all the backup and Restoration Information to the client, and then the ui. tabs folds the two types of information and displays them separately. tabs provides ajax functions for me. Each of our tabs can apply another page directly. For examp

Use AngularJS and PHP Laravel to implement single-page comments. angularjslaravel Full: https://github.com/scotch-io/laravel-angular-comment-app At present, Laravel and Angular have become very famous tools in the world of Web development. Laravel is famous for introducing great content to the PHP community. Angular is famous for its amazing front-end tools and simplicity. Combining these two frameworks seems to be a logical next step. In our use envi

the Bind method to generate an anonymous function that already contains two parameters. The code is as follows:var urls=paths.map (Simpleurl.bind (null, ' http ', ' www.cnblogs.com '));The call to Simpleurl.bind produces a new function that delegates to Simpleurl. The first parameter of the Bind method provides the value of the recipient. You can use null or undefined because you don't need it here. The remaining parameters of the Simpleurl.bind together with all the parameters provided to the

Java uses recursive and cyclic methods to implement the Cartesian Product algorithm example of an unknown dimension set. This example describes how Java implements Cartesian product of an unknown dimension set based on recursion and loops. We will share this with you for your reference. The details are as follows: What is Cartesian product? In mathematics, the Cartesian product of two sets of X and Y, also known as the straight product, is expressed a

Client callback provided by Asp. Net 2.0 Asp. Net 2.0 has been released. 2.0 has many new features, and client callback is one of them. Client callback allows us to call methods on the server without sending back. It is consistent with the functions provided by AJAX, but it is not as flexible as AJAX. AJAX can customize the called methods, the callback function provided by 2.0 does not work. To use the client callback function, you must implement the
